The Sync page

Selecting Sync (A) from the Main Menu allows the sync settings to be viewed and changed. AIXpressor provides three priority tiers: Choice 1, Choice 2, and Fall Back for automatic failover.

Sync Source Priority

The Sync Source Priority section (B) is used to define the sync source for Choice 1, Choice 2, and AES3.

  • Choice 1 and Choice 2 - Options include Internal, tieLIGHT/MADI 1, tieLIGHT/MADI 2, Sync-In WCLK/BB/Tri-Level, Interface Slot 1, Interface Slot 2, Interface Slot 3, Interface Slot 4, AES Select, and PTP. If none of the pre-selected sources in Choice 1 or Choice 2 are present, sync will fall back to Internal in order to maintain audio transport, even if this causes audible clicks and pops due to asynchronous conditions.

  • AES3 Select - The drop-down menu is used to pre-select the sync source when Choice 1 or Choice 2 are set to use AES Select as their sync source. Options include Sync-In AES3 (Sync-In BNC) and Inputs AES3 1/2, 3/4, 5/6, 7/8.

Current Sync Source Status

The Current Sync Source Status section (C) provides information about the sync source currently in use.

  • Current Sync Source - Displays the current sync source.

  • Current Sample Rate - Indicates the current sample rate, which in this firmware version is fixed to 48kHz.

  • Current Video Rate (fps) - Shows the current video rate (23.98, 24, 25, 29.97, 30, 50, 50.94, and 60).

System Clock

The System Clock section (D) sets the primary and fallback sample rates and video rates.

  • Sample Rate (kHz) - Sets the preferred sample rate (currently limited to 48kHz).

  • Internal / Fallback Sample Rate (kHz) - Sets the internal (fallback) sample rate (currently limited to 48kHz).

  • Video Rate (fps) - Sets the preferred video rate (Follow Input, 23.98, 24, 25, 29.97, 30, 59.74, 60).

  • Internal / Fallback Video Rate (fps) - Sets the internal (fallback) video rate (23.98, 24, 25, 29.97, 30, 59.74, 60).

Sync Source Information

The Sync Source Information table (E) provides an overview of the available sync sources and their values. Information includes Sample Rate and Video Rate (fps) for each source.
